AUTOMATIC PUMP.

' Specification of Letters Patent.

Patented Feb. 24;, 1914.

Application filed January 9, 1913. Serial No. 741,019.

To all whom it may concern:

Be it known that I, EDWARD J. THAYER, a citizen of the United'States, residing at Independence, in the county of Polk, State of Oregon, have invented certain new and useful Improvements in Automatic Pumps; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to steam vacuum water elevators and has for an object to provide a combined hot and cold water system of this character that may be drained easily in cold weather to prevent freezing.

A further object of the invention is to provide a pumping mechanism which will automatically operate periodically at intervals of about five minutes to raise a quantity of water into the storage tank.

With the above objects in view the invention consists of certain novel details of construction and combination of parts hereinafter fully described and claimed, it being understood that various modifications may be made in the minor details of construction within the scope of the appended claims.

In the accompanying drawings forming part of this specification: Figure 1 is a diagrammatic side elevation of my invention with parts in section. Fig. 2 is a detail perspective view of the spray nozzle. Fig. 3 is a sectional view showing one of the check valves. Fig. 4 is a longitudinal sectional view through a modification of my invention for use in deep wells. Fig. 5 is a fragmentary cross sectional view taken on the line 5-5 Fig. 4:.

Referring nowto the drawings in which like characters of reference designate similar parts, a hot and cold water system suitable for individual houses is shown, and comprises in general a steam vacuum pump cylinder 10 which is connected at the bottom with the well 11 by a water pipe 12 that is provided at suitable intervals with check valves 13 to prevent retrograde movement of water in the pipe. The water drawn into the pump cylinder is discharged therefrom into a storage tank 14 preferably situated in the garret of the house and having a gage 14', by means of a water pipe 15, said tank being equipped with the usual overflow pipe 16.

For effecting the periodical suction and discharge of water from the pump cylinder at intervals of about five minutes, a steam generating coil 17 disposed within the cookmg range 18 is connected at the top to a steam cylinder 21 by means of a pipe 22 having a manually operatable valve 23 to control the passage of steam therethrough. The steam cylinder is connected to the steam space of the pump cylinder by means of a pipe 25 which opens through the top of the pump cylinder and discharges steam downward Within the cylinder.

A bearing sleeve 26 surrounds the water discharge pipe 15 within the cylinder, and an annular float 27 surrounds this sleeve and is slidably attached thereto through the instrumentality of rollers 28. The entering steam forces the float and the water in the pump cylinder downward, the water passing up through the discharge pipe 15, the downward movement of the float being limited by a stop collar 29 carried on the lower end of the sleeve. The pump cylinder is entirely filled with steam after evacuation of the water, and this steam is now cooled by a cold water spray as will be presently described with a resultant condensation of steam and formation of a partial vacuum within the pump cylinder whereby water is drawn up into the cylinder from the well through the intake pipe 12.

For supplying the cold water spray, a water pipe 30 of relatively small diameter leads fro-m the storage tank 14: and enters the top of the pump cylinder, and is further equipped above said cylinder with a vertically disposed coil 31 which produces a water seal. The pipe is terminally equipped with a-laterally directed spray nozzle 32 of the general shape shown in Fig. 2, which nozzle has a small discharge opening 33 that discharges water against the top of the cylinder from which it is deflected in a spray. A bypass 34 is connected to the spray pipe 30 above the water seal therein and is itself provided with a vertically disposed convolution 35 forming a water seal. The bypass is connected to the steam cylinder and is provided with a check valve 36 to prevent steam entering from the steam cylinder, and is further provided with a manually controlled stop valve 37.

In operation the steam pushes the Water in'the pump cylinder down and out through the pipe 15. The steam passes around the edges of the float after the latter engages with the stop collar and follows the water out, going with a jump, which releases a check valve 30 in the spray pipe 30, thereby letting a stream of cold water enter and spray through the steam in the pump cylinder with a resultant condensation of steam and formation of a vacuum to raise the water from the well as above described. All of the steam does not follow the water out, only just enough to release pressure on the check valve 30 in the spray pipe. At the same time the spray pipe delivers water in a spray into the pump cylinder it also throws water into the steam cylinder 21 and steam coil 17 through the bypass 34, to promote another circulation of steam.

For draining the steam cylinder a drain pipe 38 is connected to the bottom of the cylinder and is provided with a stop valve 39 and adrain cock 40. The lower end of the steam generating coil is connected to the drain pipe 38 as shown at 19, so that upon opening the drain cock 40 both the steam coil 17 and steam cylinder 21 may be drained to prevent freezing when the cooking range 18 is not in use. The steam pipe 25 is provided with a relief cock 41 which permits of the pressure in a steam cylinder being relieved when desired.

The hot water apparatus comprises an upright water tank 20 which is supplied with water from the storage tank 14 by means of a cold water pipe 42 that enters the top of the hot water tank and projects nearly to the bottom thereof, this cold water pipe having a branch 43 which is equipped with a draw off faucet 44 at the sink 45. A hot water pipe 46 is connected at the top of the hot water tank and is equipped with a draw off faucet 47 at the sink. A steam pipe 48 is connected to the top of the steam coil 17 and enters one side of the hot water tank 20, this pipe having a manually operatable stop valve 49. Steam blown through the pipe into the hot water tank heats the water in the top of the tank and this hot water is drawn off through the hot water pipe 46 when desired. A feed pipe 20 for the steam coil 17 is connected to the tank near the bottom and to the pipe 38 as shown, and is controlled by a stop valve 49.

When the device is pumping the hot water tank is cut out, the valve 49 in the pipe 48 r and the valve 49 in the pipe 20 being closed to attain this end. When the device is not pumping the hot water tank is in use, and to attain this end the valve 23 in the pipe 22 and valve 39 in the pipe 38 are closed to prevent steam entering the steam cylinder.

In Fig. 4 a modified form of my invention is illustrated which modification is designed for use in deep wells and for use where the hot water system is not required. Referring now to the figure, 5O designates the pump cylinder which is suspended within the well 51 and is equipped in the bottom with an intake pipe 52 that terminates below the water level in the well and is provided with check valves 53. The discharge pipe 54 extends down through the top of the cylinder and terminates near the bottom thereof and conducts the water from the cylinder to a storage tank 55, this pipe being equipped with a check valve 56 and also with a stop valve 57. A steam pipe 58 opens through the top of the cylinder and also opens through the top of a steam cylinder 59.

Steam enters the steam cylinder and forces the water downward therein and up through the discharge pipe 54 as above described, there being a sliding float 6O fitting on a bearing sleeve 61 which surrounds the discharge pipe within the cylinder and is equipped with a stop collar 62 to limit downward movement of the float. A cold water jet pipe 63 is connected to the storage tank 55 and enters the top of the pump cylinder, and is terminally equipped with a spray nozzle 64. A steam pipe 65 is connected to the pipe 63 and to the steam cylinder and times the actuation of the spray to cause a vacuum in the pump cylinder at the proper time as above described.

A steam coil 66 is secured to the cooking range 67 and is connected by a pipe 68 to the bottom of the steam cylinder 59 and by a pipe 69 to the side of the steam cylinder, the water supply for the coil being led from a tank 70 preferably carried on the cooking range, to the steam coil by means of pipes 71 and 72. The pipes 68, 69, 71 and 72 are controlled by stop valves 68, 69, 71 and 72 respectively, which valves may be closed to prevent the water circulation through the steam coil in cold weather.

It will be noted in connection with the modified form of the invention above described that the pump cylinder is mounted in the well without alterations being made to the well. In order to drain the steam cylinder in cold weather a drain cock 73 is mounted in the steam coil pipe 68, and furthermore a relief cock 74 is secured in the steam pipe 58 to relieve the steam pressure should the same become abnormal. The steam pipe 65 which controls the admission of the cold water spray is equipped with a stop valve 75 for preventing backing up of water into the steam cylinder when the pumping apparatus is not in use.
